A friend is purchasing a condo soon and I would like to get him an SVS as a little house-warming gift. He has never had a home theater system and I would like to get him off to a good start. The two models I am currently considering are the PB10-ISD($430) and PB12-ISD($600). I like the price of the PB10-ISD. I think it has a built-in limiter, which I would consider a positive. That way, my friend would never experience port noise or bottoming-out noise, things that might cause non-enthusiasts to question the quality of the product. I assume the PB10 has less output capability than the PB12, which is not necessarily a bad thing for someone living in a condo. I am considering the PB12-ISD because while the PB10 is probably an outstanding taste of SVS, I don't want him to have to upgrade anytime soon. I think the PB12 with its greater output capability may be a bit more future-proof. Plus, my friend seems to be more impressed with loudness than with quality or accuracy. I am hoping that he will be able to appreciate deep bass. What I really want to get him is a model with the parametric EQ, like the PB12-Plus. A single room mode can severely mask the capabilities of a good sub, so the integrated EQ would be extremely useful. I would rather he not have to get a BFD. Unfortunately, I don't think I can stretch my budget that far. I know a cylinder sub would be more cost effective in this situation, but I have had some issues with my own 25-31PC+ that make me reluctant to give one as a gift. As weird as it sounds, I have experienced port and grill noise, and don't wish for my friend to experience the same thing. My friend is a bit brand-name oriented (Bose, Sony), and since SVS is not a mainstream brand, I would prefer a relatively bulletproof model that will never cause my friend to doubt the SVS brand. In summary, the goal is accurate bass for an impressionable home theater novice living in a condo. I would appreciate any feedback. Thanks!
